What is two-factor authentication (2FA)?

September 26, 2023

In the digital world, security is paramount. That's where two-factor authentication (2FA) comes into play. But what exactly is it? Let's dive in and explore how 2FA enhances your banking experience with bunq.

Understanding 2FA

Two-factor authentication, or 2FA, adds an extra layer of security to your online accounts. It requires not only a password and username but also something that only you have on you, like a piece of information only you should know or have immediately on hand - like a physical token.

How Does 2FA Work?

When you enable 2FA, you'll need to provide two pieces of evidence (your factors) before you can access your accounts. These factors could be something you know (like a password), something you have (like your phone), or something you are (like your fingerprint). This means even if someone knows your password, they still won't be able to access your account without the second factor.

Why is 2FA Important in Banking?

In the context of banking, 2FA provides an extra layer of protection against fraud and identity theft. With 2FA enabled on your bunq account, you can rest easy knowing that your money and personal information are safe.
